Tundra, this would depend on a number of factors. Temp, battery size, freezer wattage. Freezers don't run all the time, depends on the temp.
You might be able to get a decent idea on how much it uses by hooking up a Kill A Watt usage meter for a couple days with the freezer in it's normal fill level and it already at temp. Good hardware stores carry them. Being March, you may want to bring the freezer in the house to try it although even that won't simulate a 90 degree day. Using an hours average wattage you can get an estimate of how long your battery will last, at whatever ambient temp you test it at, not counting any input from the tow vehicle.
